I wanted to start a new thread and will be locking my old thread so people can learn and take preventative measures...

BS3 has been repaired. Also learned two nuggets of info relating to my problem which I want to share.
My problem was a blown out IAC and secondary chip. This is caused by charging a 16V system with it powered. I always try to kill the main power switch on the car when charging (everything including BS3 is on the switched side) but must've forgot it once. MAKE SURE YOU DON'T CHARGE 16V BATTERIES WITH THE BS3 POWERED
Coil dwell with 16V systems (including the Caspers volt booster) DO NOT USE MORE THAN 4ms DWELL TIME. Upping to 6ms dwell is a common thing done at these power levels, but this is only for 12V systems. If you use 16V battery or up the alt voltage to 16V at WOT via the casper volt booster then set max dwell to 4ms.
BS3 is adding this info to their FAQ section since it was definately not common knowledge until now...

Who knows, I worked with high power RF systems for years and its amazing what a little EMI or a voltage spike here and there can do to electronics. A race car is not a friendly environment for electronics thats for sure. One spark on the battery terminal from an older transformer charger can hurt a lot of stuff..

I never did (at least intentionally)...thats whats bugging me...I really think it was related to that faulty charger I had...at the time...I had my BS3 power wires hooked directly to battery per the instructions. after that incident...I moved them to the switched side of my kill switch...

Brian,
Good for you now you've found the problem. I'm sure you now have a renewed interest in your car. Sometimes problems like this can sure hurt the moral. Well at least you know you have some good friends here on the board that offered you some encouragement. Good luck getting into the 7's!!!![Mr. Cool](https://ls1tech.com/forums/images/smilies/LS1Tech/gr_cool.gif)
